One thing that's very interesting to us that is using this rapidly-produced thing then becomes a 'social object': creating conversations, collecting scribbles, instigating adventures - which then get collected and redistributed.

In some places, participants are creating the first freely-available maps by GPS survey. In other places, such as the United States, basic roads exist, but lack local detail: locations of traffic signals, ATMs, caf'es, schools, parks, and shops. What such partially-mapped places need is not more GPS traces, but additional knowledge about what exists on and around the street. Walking Papers is made to help you easily create printed maps, mark them with things you know, and then share that knowledge with OpenStreetMap.
